🤖 Auto-Detect Your Preset

import { autoDetectPreset } from '@tthbfo2/firebase-db-optimizer/presets';

// Let the optimizer suggest the best preset based on your collections
const detection = autoDetectPreset({
  collectionNames: ['products', 'orders', 'cart', 'inventory'],
  readWriteRatio: 10, // optional: 10 reads for every 1 write
});

console.log(`Recommended: ${detection.preset}`);
console.log(`Confidence: ${detection.confidenceLevel}`);
console.log(`Reason: ${detection.reason}`);

// Use the detected preset
const presetConfig = getPreset(detection.preset);

Strategy: Start with "balanced" for free, let the auto-detector tell you if a specialized preset would be worth upgrading to when paid tiers launch.

📦 Payload Trimming (v0.6.5)

Reduce network egress by up to 90% with the fields parameter - available to all users (free feature):

Note: Free tier supports top-level fields only. Advanced payload trimming (nested paths, wildcards, array slicing) available in Pro/Enterprise tiers.

// Only fetch specific fields to reduce payload size
const product = await optimizer.readDocument('user1', 'products/123', {
  fields: ['name', 'price', 'inStock']  // Reduce payload by 90%
});
// Returns: { name: 'Product A', price: 99, inStock: true }

// Still caches full document for cache integrity
const fullProduct = await optimizer.readDocument('user1', 'products/123');
// Returns: Full document with all fields (served from cache!)

How it works:

Always fetches and caches the full document from Firebase
Trims payload before returning to your app
Future requests for different fields are served from cache
No cache integrity loss, maximum network savings

📊 Real Performance & Query Optimization Results

Test Environment: Firebase Emulator with real SDK calls (Firestore query performance benchmark) Test Date: October 12, 2025 Methodology: 115 operations with 70/30 hot/cold split

Firebase Reads: 112 → 35 (68.8% reduction)
Cache Hit Rate: 69.6% (80 cache hits / 115 operations)
Cost Savings: 68.8% ($3.36 → $1.05 per 1K operations)
Error Rate: 0% (100% reliability)

Real-world validation confirms:

✅ Uses genuine Firebase SDK (getDoc, getDocs, onSnapshot)
✅ No mocked data or artificial performance boosting
✅ Enterprise-grade security enforced
✅ Multi-tier L1/L2/L3 caching with proper TTLs

🛡️ Performance Monitoring

The optimizer monitors your performance and provides insights:

// Performance monitor runs automatically in background
// Validates cache hit rate meets expectations

✅  Firebase Optimizer: Performance Summary

Current Preset: 'balanced'
Expected Cache Hit Rate: 45-60%
Actual Cache Hit Rate: 52%
Status: ✅ Performing as expected

Cost Savings: 52% reduction in Firebase reads

🔒 Security Features

User Isolation: Complete separation of user data in cache and operations
Data Sanitization: Automatic removal/masking of sensitive information
Permission Verification: Real-time access control with role-based filtering
Audit Logging: Comprehensive security event tracking
Compliance Ready: GDPR, HIPAA, PCI-DSS compatible presets

🔧 How It Works

Firebase DB Optimizer uses a three-tier caching architecture to optimize Firestore query performance:

Multi-Tier Cache Strategy

L1 Cache (Memory): Ultra-fast in-memory LRU cache (~100μs access)
L2 Cache (Process): Process-level Map cache (~500μs access)
L3 Cache: Extended TTL in-memory cache for cold data (up to 30 minutes)

Request Flow

// When you request data:
const product = await optimizer.readDocument('user1', 'products/123');

// Behind the scenes:
// 1. Check L1 → L2 → L3 caches (90% hit rate on hot data)
// 2. If cache miss: Fetch from Firebase, populate all tiers
// 3. Respect collection-specific TTLs (e.g., products: 10min, cart: 2min)
// 4. Trim payload to reduce bandwidth before returning
// 5. Cache full document for future requests

Key Optimizations

Query optimization: Repeated queries served from cache (60-90% faster)
Bandwidth reduction: Payload trimming reduces network egress up to 90%
TTL management: Collection-specific time-to-live prevents stale data
Security enforcement: All reads/writes pass through security layer

🆚 Why Choose This Optimizer?

✅ Local-First Architecture

Unlike cloud-based Firebase caching solutions (Redis, Memcached), Firebase DB Optimizer runs locally in your application:

✅ No external dependencies: No Redis server, no cloud fees
✅ Zero latency overhead: Cache is in-process (100μs vs 10ms+ for Redis)
✅ Privacy-first: Your data never leaves your infrastructure
✅ In-memory architecture: Fast, secure, no external storage required

✅ Built for Modern Deployments

Perfect for modern deployment environments:

Serverless functions (AWS Lambda, Vercel, Netlify): In-memory caching per invocation
Container environments (Docker, Kubernetes): Process-level caching
Traditional servers (Node.js, Express): Full L1/L2/L3 support

✅ Firebase-Native Integration

Designed specifically for Firebase/Firestore (not a generic cache):

Collection-aware TTLs
Firebase SDK compatibility
Security rule preservation
Real-time listener support
